We hope that the children in the study will lay the foundation for mathematics and all the learning. Wish they have more happy explorations to prepare well for the road to be the scientists, even the Nobel Prize in the future.

The Nobel Prize in Chemistry 1986 was awarded jointly to Dudley R. Herschbach, Yuan T. Lee and John C. Polanyi "for their contributions concerning the dynamics of chemical elementary processes.

“From this book I can clearly see that you (the author) are dedicated to the fundamentals of education. I believe that many children will be able to appreciate the beauty of math.”Director Liao Junzhi, Academia Sinica

Dr. James C. Liao , presentPresident, Academia Sinica 2016 -

The two world scientists have extraordinary achievements in their respective fields. Their fields are different, they both have won the world-class ultimate awards in their respective fields.They both have served as President, Academia Sinica. Fortunately, the current President, Academia Sinica recommends 123 Easy Teaching. After you read the content of this website, there will be such a feeling. 123 Easy Teaching is very helpful to the children's arithmetic guidance.If you want to quickly understand the efficiency and effectiveness of 123 Easy Teaching to get the effective and effective learning methods on arithmetic, you can directly click "(+ − × ÷) Door Open" to see the guide of the book. It explains the important concepts and design features.

Dr. James C. Liao has been named co-winner of the 2013 Eni Prize for renewable energy research. Awarded from President of Italy

This book succeeds in using cute illustrations to draw children into the beautiful world of math. It allows children to personally reason about numbers and realize the relationship between them, similar to how the keys of a piano come together to make a melody. I believe that this way of learning will provide lifelong benefits to the children. I think this book is strongly worth recommending and for parents and their children to read along together.Professor Lin Tai-Chia, National Taiwan University

“Early childhood education is the most critical stage of learning; a poor early start will have lasting effects on later development. In my own personal experience, I have found that students often have the most trouble with mathematics. It is truly a shame that many students often give up on math due to falsely perceived difficulty. Teacher Huang's innovative new work, 123 Easy Teaching, is the result of many years of teaching experience. This book series addresses the needs of youth education and eliminates the difficulties and bottlenecks frequently encountered during the elementary learning process. This allows children to gain confidence in their mathematic abilities, furthermore, it allows them to learn happily without struggle. These books are vital to providing a solid arithmetic foundation for children.”Zhang Huatang, President of Hukou Senior High School

AcknowledgementsThe creation of 123 Easy Teaching would not have been possible without the invaluable advice from established educators in the field. I would like to specially thank the following individuals for their approval: ⦁ Professor Lin, Mathematics Department, National Taiwan University⦁ Professor Huang, Applied Math Department, National Dong Hwa University⦁ Professor Fu, Applied Math Department, National Chiao Tung University

I would like to thank Professor Lin of National Taiwan University for his ideas on improving the text. In addition, I would like to thank the dean Bao of Northeast Agricultural University and Principal Zhang of Hukou High School for their sagacious advice. For many years, they have propelled their many students to academic success. I extend my gratitude to the dean Li of National Tsinghua University for establishing a youth education foundation, to guide students with their homework and guide them along with the course material. I would also like to thank the internationally renowned Director Liao of Academia Sinica, the national academy in Taiwan, for his praise. To all of these individuals, I would like to once again expressed my heartfelt gratitude.

To receive the recommendations regarding 123 Easy Teaching from these scholars has been an honor. I also hope that this work can received widespread support and use, so please spread the word to help support children everywhere have a smooth introduction to arithmetic.

Note: Academia Sinica was founded in 1928 in Nanjing, with Dr. Cai Yuanpei as the first director. Now Academia Sinica is locate in Taipei, with Dr. Liao Junzhi as the director. The academy has fostered brilliant minds such as that of Yuan T Lee, the first Taiwanese Nobel prize laureate, who acted as the academy directed from 1994 to 2006.

The 123 Easy Teaching expressed in native English written by some famous and professional American scholar.

According to the logical sequence and regularity of the traditional 9* 9 multiplication table , the logic of various operations is editted in 123 Easy Teaching. The primary school students are familiar with such a nature when they learn the addition and subtraction.Practice makes perfect, if the 123 Easy Teaching is applied to learn addition and subtraction well, the students are able to be very accustomed to use such a nature to learn the nine-nine (or 12* 12 ) multiplication table in the future.

"We believe every child can become a numerate adult. " This Book 123 Easy Teaching makes children totally change their calculating habits, and children are able to get the calculating results as quickly as adults.

PrefaceRecently, the British Ministry of Education has begun to question the value of rote memorization of multiplication tables and the notion that not memorizing one’s multiplication tables will result in inferior arithmetic abilities. One senior official has proclaimed that if Britain does not change the way mathematics is taught in schools, then the British economy will decline. In 2016, Britain decided to continue having children memorize the 12x12 multiplication table. However, when elementary school principals visited China, they were shocked by the 9x9 multiplication table in use there.

Memorizing the 9x9 multiplication table is greatly beneficial for young children studying math. Furthermore, developing fundamental arithmetic skills is similarly critical to developing a child’s confidence in math.

Visual learning has been demonstrated to be one of the most effective methods of teaching to children. The visual aids in 123 Easy Teaching are simple yet clear, allowing for children to learn the intuitions behind arithmetic. Through consistent and thorough study, children will subconsciously develop confidence and a rich interest towards math. We hope that all the students and teachers using this book will have this kind of experience.All rights reserved.
